Abstract
Transient contrast enhancement on computed tomography following endovascular treatment of stroke is a recognized entity that has been previously reported. Technological advances in brain imaging now have the potential to explore and refine its proposed etiology. We describe three patients in whom the location of contrast enhancement correlates with decreased cerebral blood volume on pre-therapeutic CT perfusion studies and with restricted diffusion on MRI. In this regard, contrast enhancement demarcated areas of completed cerebral infarction. The diagnostic and etiological implications are discussed.
摘要
卒中血管内治疗后计算机断层扫描上的短暂性对比增强是一种已被先前报道的公认现象。脑成像技术的进步现在有潜力探索并完善其推测的病因。我们描述了三名患者，其对比增强的位置与治疗前CT灌注研究中脑血容量减少以及MRI上的扩散受限相关。在这方面，对比增强划定了完全性脑梗死的区域。本文讨论了其诊断和病因学意义。
